Do you know "XENON-80" ?
click the picture, you can see big sized one.

XENON-80 is Z-80A based hand-made microcomputer.                   Do you see more ?

Please solve my question
I had found *experimentally* that
there are difference about the handling of "CTS"
in Intel i8251A and NEC uPD8251A.

  if "CTS (Clear To Send)" negation is occurred while sending,
  Intel i8251A *re*-send the data automatically *again*
  after next "CTS" assertion.
Is this specification of Intel i8251A ?

!= ?

(2007.3.27)  I've got both 8251 datasheet from Alldatasheet.com and found a hint !

Who is he ?
